Chess Impairment

Alright, listen up, buttercup. This joke is dark. It's saying Americans can't play chess because they "lost two towers." This is a reference to the September 11 attacks, where the Twin Towers of the World Trade Center were destroyed. The joke is that losing the "two towers" in 9/11 means they can't play chess because they lost their two rooks (which are also sometimes called towers). Get it? Bet you didn't, you snowflake.
